Patent

CA 2156958

Here is disclosed an improved nonwoven fabric wiper obtained by a method comprising steps of forming a laminate from a web of thermally shrinkable hydrophobic synthetic fibers and a web of hydrophilic fibers put one upon another, jetting high pressure water onto the laminate supported on a supporting roll provided on its peripheral surface with a plurality of fine projections as well as a plurality of drainage apertures, causing the fibers to be entangled or intertwined and rearranged and thereby forming a nonwoven fabric having uneven fiber distribution densities, and heating the nonwoven fabric to crimp the synthetic fibers so that only portions of relatively high fiber density may bulge.
